I perm’d the ‘Skull and Cross’ sticker before the last patch.
I own two (now three) Federation frigates. An Alligator-C and Alligator-M (and the Alligator mk. 2). The sticker does not display on the right-rear quarter of the ship. I tried previewing other stickers to see if it would fix itself, but so far every sticker is bugged in the same manner. I also tried removing and re-applying the sticker.
Not a game-breaker, just odd.
